Here are IOPA (Intraoral Periapical) radiographs of carious teeth:

IOPA Radiographs of Carious Teeth

Image 1 - Multiple IOPA views (DenPAR dataset)

IOPA radiographs showing various dental conditions including caries

(a) Posterior teeth with visible radiolucency in the crown area indicating caries
(b) Bitewing-style posterior view showing interproximal and occlusal caries (dark areas in crowns)
(c) Anterior teeth IOPA
(d) Anterior teeth with clear root and periapical detail

Image 2 - Posterior molar IOPA showing deep caries

IOPA radiograph of posterior teeth with caries

This IOPA shows posterior molars with radiolucent areas in the crowns consistent with carious lesions, along with visible root canals and periapical bone.

Radiographic Features of Caries on IOPA

Feature	Appearance
Enamel caries	Small triangular/wedge-shaped radiolucency at the enamel surface
Dentinal caries	Larger, deeper radiolucency extending toward pulp
Occlusal caries	Dark shadow in the center of the occlusal surface
Interproximal caries	Radiolucent notch just below the contact point
Deep caries near pulp	Large radiolucency approaching or reaching the pulp chamber
Periapical changes	Widened PDL space or periapical radiolucency if pulp is involved

Key radiographic principle: Caries appear as radiolucent (dark) areas on IOPA because decalcified/destroyed tooth structure absorbs less X-ray radiation than intact enamel and dentine. The IOPA is best for visualizing the full tooth length (crown to root apex) and detecting periapical pathology that may result from advanced caries progressing into the pulp.
